Abstract
Many synthetic latices are produced with a small particle size. It is desirable to increase the particle size and concentrate the latex. It is known to use agglomerating agents to increase particle size. The temperature of agglomeration may be reduced if the latex is destabilized with a weak acid, preferably carbonic acid. This results in an energy saving for the process.
